How early-life colonization and subsequent exposure to the microbiota impact long-term tissue immunity remains poorly understood. Here we show that the development of mucosal-associated invariant T (MAIT) cells relies on a specific temporal window, after which MAIT cell development is permanently impaired. This imprinting depends on early-life exposure to defined microbes that synthesize riboflavin-derived antigens. In adults, cutaneous MAIT cells are a dominant population of IL-17A-producing lymphocytes, which display a unique transcriptional signature and can subsequently respond to skin commensals in an IL-1-, IL-18-, and antigen-dependent manner. Consequently, local activation of cutaneous MAIT cells promotes wound healing. Together, our work uncovers a privileged interaction between defined members of the microbiota and MAIT cells, which sequentially controls both tissue-imprinting and subsequent responses to injury. Early-life microbial exposure imprints the abundance of mucosal-associated invariant T cells and subsequent interactions with the microbiota modulate their ability to promote tissue repair.
